i the reception of the branch pipes 12d and 13.

The upper end ofvthis casing is also preferably provided with an opening 19, which when the branch pipes are used maybe closed with a plug 20, and when the branch pipes are n`ot used a continuation of the main pipemay be connected thereto. In this casing I mount a heating element,'which may be of any suita'blefform or construction, but

In a heat generating and. radiating sys tem, the combination with a'generator, andtem, an auxiliary heating coil located within Y and 'extending longitudinally, of said casing, and Vlocated vto .cause the heating'medium to pass through the axis ofthe coil and also between the convolutions thereof, and a separate reservoir connected with said auxiliary heating coil.
